Renato Golin 39dd163cdb Improve check on git-svnrevert, better error message ... When the commit is not in the tree at all, find-rev returns 0 and prints an empty string. We need to catch that problem too, when trying to revert. Adding a list of possible problems, so that you can easily and quickly correct without having to edit the script again. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@237516 91177308-0d34-0410-b5e6-96231b3b80d8		2015-05-16 10:23:48 +00:00
